for me hibernation is to:
2. Kill noise
3. save energy
One thing I hate is, so many mysterious processes running there I don't know what they are doing? Sending my personal data, location, user statistics etc. to Synology?
Many times at night while watching TV and no one access NAS, the NAS is quite noisy doing something... I unplug the LAN cable, all quiet!! That's fine, nobody is accessing NAS.
and now I always set hibernation to 10min, most of time it is quiet and unnoticeable there.
...and at nights I even set to power it auto off and in the morning power on.
But wouldn’t “killing” the power like that without ejecting the disk first might cause problems?
I know that the DS will complain about it at least. Maybe you’ll need to come up with a scheduled script to eject it first before the timer kicks in and kills the power.
While I'd not be a fan of using a kill switch (timer switch) for a USB disk doesn't Hyper Backup have a setting to unmount/eject the disk at the end of the task?
So long as you don't use the disk for anything else but this backup task then the disk should be in a quiet state after HBup unmounts it. The timer switch could be set to turn off well after the end of the expected task run and then on again before the task.
I wrote a Launch Agent and script for Mac to mount and unmount disks based on a cron-style time schedule ... that need has long since passed but I still use it manually to unmount my backup disks when I login.
